11760µF capacitance per module
Current, voltage and temperature measurement
Interfaceboard with signal processing
General information:
VARIS™ XT consists of six half bridge IGBT modules with 21 dc-link capacitors. All semiconductors are
placed on one cooling plate for a perfect homogenous cooling. Its modular design allows paralleling of the
AC-output/input as well as paralleling of the dc-link with other VARIS™ XT. Possible circuit arrangements are
active front end topologies, two single three phase inverters, and one three phase inverter with almost twice
the power of a single three phase inverter through direct paralleling or soft paralleling via external balancing
inductors.
An interfaceboard located on the front of the VARIS™ XT summarizes all IGBT signals as well as voltage,
current and temperature measurements.

1. General Circuit Arrangements:
The following figure shows the general circuit arrangement. VARIS™ XT can be divided into six half bridge modules (P1-P6) that are all connected to one DC-link.
Figure 1: Standard hardware setup
Depending on the application different circuit arrangements are possible. For higher power, all cir-cuits shown below can be expanded with additional VARIS™ XT modules.

Our IGBT modules are optimized for direct paralleling, which means they have the same Vce(sat) forward voltage among themselves. However, when using direct paralleling the current measurement has to be external. Optional current sen-sors for direct paralleling are available on request.

In a soft paralleling configuration with external balancing chokes, the included standard current sensors can be used.

3. Technical Data Interfaceboard:
The Interfaceboard is located right next to the Driverboards and summarizes the IGBT signals as well as the
AC-output current measurements, DC-link voltage measurement, and PT100 temperature measurement.
Figure 6: VARIS™ XT circuit arrangement with Interfaceboard
The board contains switches for a paralleling of the IGBT phase legs. If activated, the customer IGBT signals
are automatically split and directed to the corresponding paralleled modules.
The interfaceboard combines the IGBT highside and lowside feedback signals to one feedback signal from
each IGBT module. This minimizes the wiring effort, and still guaranties a feedback from each module.
For noise reduction all signals are filtered and amplified. A hardware interlock of the PWM signals automati-
cally shuts down the system when a short circuit or under voltage of one driverboard is detected. When the
error disappears the system goes back to normal operation.

4. Technical Data Driverboard:
Each IGBT module has its own driverboard, and all driverboard signals are brought together at the interface-
board. The signal transfer from driverboard to interfaceboard is electrical, and from interfaceboard to custom-
er control optical.
However, VARIS™ XT is also available without interfaceboard. In this case the customer can choose be-
tween an optical or an electrical driverboard signal transmission.
